To build images with these sources, your build environment should be a Debian GNU/Linux installation. To build images with "Bullseye"-version, use the "bullseye"-branch. To build images with "Bookworm"-version, use the "bookworm"-branch. The build host should probably be of the same version your target image is. As of May 2024, our main production version is Bullseye and Bookworm is under active development.
After cloning the repository, you should also update submodules (unless the repository was cloned with parameter --recursive):
git submodule init
git submodule update
To setup build host, run (with sudo or as root):
sudo make setup-buildhost
To build Puavo OS image, run:
make rootfs-debootstrap
make rootfs-update
make rootfs-image
After successful build, the built image can be found by default from /srv/puavo-os-images
Run make help to get help.
Note: As the build process scouts some parameters from the runtime environment, building it under a puavo-os session might require some manual steps not yet documented here. Building in e.g. a fresh Debian Bullseye virtual machine works with the steps listed above. Due to build process using a ramdisk /tmp, the virtual machine should have at least 16 GB of RAM for successful build.
Puavo OS image is not very useful in itself. Puavo OS is designed to be used with a Puavo Web server, that is used to manage user accounts and devices.
A Puavo OS image can be used to boot a system with PXE
in case a suitably configured network boot server
is available. To install a host with a removable drive,
a separate installation image is required.
You can try using puavo-make-install-disk to create
one, or simply check out https://puavo.org for
some example installation images.
An installation image can be booted in "live"-mode to test hardware compatibility with Puavo OS. When booted in "normal" boot mode, an installation should be performed. To install, a login to a Puavo Server is required to make it possible to manage the host. In case a Puavo Server is not available, the instructions in https://github.com/puavo-org/puavo-standalone can be followed to setup a test server. Do not use the test server in production before understanding how it works and setting up passwords properly.
The "config"-directory contains various configurations for the image.
The file "config/rootca.pem" is a CA-certificate that will be copied to image "/etc/puavo-image/rootca.pem" at image build time. The default file is compatible with the CA-infrastructure set up by Opinsys, the company behind Puavo, BUT if you are running Puavo on your own, non-Opinsys infrastructure, you should replace that with your own CA-certificate.
The values in "config/puavo_conf.json" override default values for puavo-conf variables.
